JEFFREY O. BENTLEY, OF PHILADELPHIA, PENNSYLVANIA.

STILL.

SPECIFICATION forming part of Letters Patent No. 557,102, dated March 31, 1896.

Application lecl June 4, 1895. Serial No. 551,587. (No model.)

To all whom it may concern.-

Be it known that I, JEFFREY O. BENTLEY, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Stills,which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a novel construction of still in which the water is more rapidly evaporated and purified than heretofore, the novel features of the apparatus being hereinafter set forth, and specifically pointed out in the claims.

Figure 1 represents a vertical sectional view of a still embodying my invention. Fig. 2 represents on an enlarged scale a sectional view of the upper left-hand portion of the still. Eig. 3 represents a front elevation of the same, partially in section.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, T designates the casing of the still, the same having inner and outer walls forming a-water-jacket. A designates the inlet-pipe, which conducts the fluid into said jacket. B designates a passage between a portion of awall of the still and the top or, partition WV of the same. C designates an enlarged chamber through which said water passes after entering the passage B. E designates a pipe in said chamber C by means of which communication is had with the space above the partition WV, which constitutes a heating-chamber. F designates an inlet from said pipe E to said heatingchamber.

K designates the inner lid of the top .I of the still, the same being adapted to rest in a suitable recess D, whereby communication is had for the water between the chamber C and the evaporating-chamber I, it being noticed that the said recess D is below the top of the pipe E.

L designates a tube located within the still, said tube being open at its bottom and top and having said top above the bottom of said heating-chamber and serving to introduce air into the space above the partition IV. M designates a pipe which is located within said tube L. N designates a gas-pipe which conducts the heating medium into the upper portion S of said pipe IWI, said portion S being perforated `to allow the ignition and escape of the heating medium.

P designates an open-ended pipe which forms a comm unication between the chamber or reservoir I and the condensing-chamber R in the lower portion of the still.

IV designates the bottom partition of the still; H, an overliow, and V a cock or pipe whereby the water of distillation is drawn off.

The operation is as follows: The gas or other heating medium having been ignited heats the bottom of the reservoir I. The water is introduced in the pipe A and iills the jacket T and passes in the direction indicated by the arrows in Eig. 2 by means of the passage D into said reservoir I, the heat evolved from the burner S heating the bottom of the reservoir, so as to vaporize the water flowing thereinto, the steam from which passes through the pipe P into the enlarged distillation-chamber R and is there condensed, the distilled water being drawn off from the bottom through the pipe V, the air for combustion being introduced through the perforations below the reservoir I in the sides of the casing as well as through the open end of the tube L.

The quantity of water in the evaporatingchamber is controlled by the pipe E, any eX- cess above the top of the same owing down said pipe into the heating-chamber and out through the overflow-pipe II.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A still, consisting of a condensing-chamber, having a water-jacket with an inlet-pipe, a heating-chamber directly above and supported on said condensing-chamber, and having openings in its sides, an evaporatingchamber above said heating-chamber, an enlarged chamber outside of and communicating with said water-j acket and evaporating-chamber, a pipe leading from said heating-chamber into said enlarged chamber above its communication with said evaporating-chamber, a pipe leading from the upperpart of said evaporating-chamber into said condensing-chamber, an overiiow-pipe leading from said heating-chamber, and means for heating the latt-er, said parts being combined substantially as described.

IOO

2. A still, consisting of a condensing-chamber R', having a Water-jacket with an inletpipe, the heating-chamber above said eon- (lensing-chamber, an evaporating-ehalnber above said heating-chamber, the enlarged chamber C communicating With said Waterjacket and evaporating-ehamber, the pipe E communicating with said heating and enlarged chambers and having its top above the Communication between the said enlarged chamber and the evaporating-ehamber, the open-ended tube L located Within the still and having its top above the bottom of the heating-Chamber, the pipe M Within said tube L, having its perforated top above the top of said tube, and a gas-supply pipe leading into JEFFREY O. BENTLEY. lVitnesses:
